Compact Trapezoidal-Shaped Monopole-Like Slot UWB Antenna for WBAN Applications

A novel compact coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna comprising of a trapezoidal-shape monopole-like slot and a CPW fork-shared feeding structure is presented. The proposed antenna offers a compact size of 25 mm x 28 mm x 1.5 mm and a FR-4 dielectric substrate with dielectric constant of 4.4, aiming to achieve a wide operating bandwidth of 2.7 GHz to 13.0 GHz (137%). Extensive computer simulation studies were conducted to validate the feasibility of the proposed antenna for wireless body area network (WBAN) applications.
